You might not agree with all of the conservative grassroots movement, but, after reading this, you will find it difficult to call us "extreme radicals" unless you see God, country and allegiance as foundation stones for new age radicalism.

Succinctly put,  the tea-party grassroots movement is united in the following 10 briefly stated concerns:  

1. Protect the Constitution
2. Reject Cap & Trade (there are other ways to deal toxic emissions)
3. Demand a Balanced Budget (who knew the Dems oppose this?)
4. Enact Fundamental Tax Reform
5. Restore Fiscal Responsibility & Constitutionally Limited Government (when conservatives refer to "limited government," they are talking more about the expansion of the federal and central government,  returning decision making power back to local and state governments.  The tea party is not against "government," per se). 
6. End Runaway Government Spending
7. Defund, Repeal, & Replace Government-run Health Care
8. Pass an ‘All-of-the-Above” Energy Policy (we have more tahn a 100 year supply of fossil fuel.  We have time to transition to alternative fuels with driving poor people out of their homes and cars). 
9. Stop the Pork (period and forever). 
10. Stop the Tax Hikes (especially those hikes intended to fuel central government growth and idiot federal policy).  

Here is the Contract from America,  signed by 70  Republican and libertarian congressional folks.  No Democrats ventured across party lines,  as dictated by Reid and Pelosi.

From a separate grassroots movement,  we have this wording  -  in essence,  very much the same as the actual "contract."  

1.   Identify constitutionality of every new law: Require each bill to identify the specific provision of the Constitution that gives Congress the power to do what the bill does (82.03%).  

2.   Reject emissions trading: Stop the "cap and trade" administrative approach used to control pollution by providing economic incentives for achieving reductions in the emissions of pollutants. (72.20%).

3.   Demand a balanced federal budget: Begin the Constitutional amendment process to require a balanced budget with a two-thirds majority needed for any tax modification. (69.69%)

4.   Simplify the tax system: Adopt a simple and fair single-rate tax system by scrapping the internal revenue code and replacing it with one that is no longer than 4,543 words – the length of the original Constitution. (64.9%)

5.   Audit federal government agencies for constitutionality: Create a Blue Ribbon taskforce that engages in an audit of federal agencies and programs, assessing their Constitutionality, and identifying duplication, waste, ineffectiveness, and agencies and programs better left for the states or local authorities. (63.37%)

6.   Limit annual growth in federal spending: Impose a statutory cap limiting the annual growth in total federal spending to the sum of the inflation rate plus the percentage of population growth. (56.57%).

7.   Repeal the health care legislation passed on March 23, 2010: Defund, repeal, and replace thePatient Protection and Affordable Care Act. (56.39%).

8.   Pass an 'all-of-the-above' energy policy: Authorize the exploration of additional energy reserves to reduce American dependence on foreign energy sources and reduce regulatory barriers to all other forms of energy creation. (55.5%).

9.   Reduce earmarks: Place a moratorium on all earmarks until the budget is balanced, and then require a 2/3 majority to pass any earmark. (55.47%).

10. Reduce taxes: Permanently repeal all recent tax increases, and extend permanently the George W. Bush temporary reductions in income tax, capital gains tax, and estate taxes, currently scheduled to end in 2011. (53.38%).
